Silver cyanide drying method

Abstract

The invention relates to the technical field of silver cyanide drying, in particular to a silver cyanide drying method. The method comprises the following steps: 1, weighing quantitative metal silver and nitric acid through weighing equipment, then weighing quantitative water and quantitative sodium cyanide, and then respectively putting the weighed materials into respective placing containers; and 2, putting the weighed quantitative silver and nitric acid into a mixing container at the same time, completely dissolving the silver, then adding the quantitative water weighed in step 1 for dilution, adding the weighed quantitative sodium cyanide into the mixed solution after dilution, and closing a shielding cover of the mixing container after the reaction is completed. According to the device, silver cyanide is pre-crushed, the drying efficiency of the silver cyanide is improved, the phenomenon that the silver cyanide is attached to the outer sides of the containing containers and is inconvenient to clean is avoided to the maximum extent, meanwhile, waste of heat energy in the drying process is avoided to the maximum extent, and the safety of the silver cyanide during drying is guaranteed.

Description

technical field [0001] The invention relates to the technical field of silver cyanide drying, in particular to a silver cyanide drying method. Background technique [0002] Silver cyanide is white or light gray powder, odorless, tasteless, and highly toxic. Inhalation of silver cyanide can cause cyanide poisoning, headache, fatigue, dyspnea, convulsions, coma, and even death. Inhalation of isoamyl nitrite Detoxification, this product is mainly used for medicine and silver plating. It should be stored in a cool and ventilated warehouse, away from fire and heat sources. The package should be sealed. It should be stored separately from oxidants, acids and food chemicals. Do not store them together. Suitable materials should be prepared to contain the leakage. Silver cyanide is usually used in medicine, silver plating, as a protective coating, autoclave lining, electrical contacts, and electroplating of aircraft engine bearings. Ether chlorine and alcohol are used to make steric...
